Resistance Decade Boxes

IET is the World's Leading Resistance Decade Box Manufacturer

With 50+ years of stability data and history, IET Labs manufactures a full line of resistance decade boxes that will cover most any budget and application: field, calibration laboratory or automated stations

From the world's highest precision to our cost-effective models1000's of models available from 1 mΩ to 10 TΩProgrammable and self-calibrating models available.Contact us if you don’t find the decade resistor you need and we would be happy to custom build it

IET Labs, maintains some of the finest R, L and C calibration standards in the World. . Almost all of IET’s resistance decade boxes are manufactured with pride in the USA.

Software leverages the accuracy of an 8.5 digit DMM, with the versatility of the PRS-300 Programmable Resistor to make the most revolutionary standard resistor ever manufactured

Resistance Range: 0.1 Ω to 20 MΩ

Resolution: 1 μΩ

Accuracies better than 20 ppm; source resistance with the same accuracy that your 8.5 Digit DMM can measure.

All you need to do is enter the target resistance. The software uses the DMM to measure the resistance being sourced by the PRS-300 and readjusts the source resistance as close as possible to the target resistance.

Software automatically provides the measurement uncertainties of every measurement
